operands
public java.lang.Iterable<Operand> operands()
Description copied from class:Expression
Get the immediate sub-expressions of this expression, with information about the relationship of each expression to its parent expression.If the expression is a Callable, then it is required that the order of the operands returned by this function is the same as the order of arguments supplied to the corresponding call() method.
- Specified by:
operands
in classInstruction
- Returns:
- an iterator containing the sub-expressions of this expression
-
copy
public Expression copy(RebindingMap rebindings)
Copy an expression. This makes a deep copy.- Specified by:
copy
in classExpression
- Parameters:
rebindings
- the rebinding map- Returns:
- the copy of the original expression
-
mayCreateNewNodes
public final boolean mayCreateNewNodes()
Determine whether this instruction creates new nodes. This implementation returns true.- Overrides:
mayCreateNewNodes
in classInstruction
- Returns:
- true if the instruction creates new nodes under some input conditions (or if it can't be proved that it doesn't)
-
getInstructionNameCode
public int getInstructionNameCode()
Get the name of this instruction for diagnostic and tracing purposes- Overrides:
getInstructionNameCode
in classInstruction
- Returns:
- a code identifying the instruction: typically but not always the fingerprint of a name in the XSLT namespace
-
export
public void export(ExpressionPresenter out) throws XPathException
Diagnostic print of expression structure. The abstract expression tree is written to the supplied output destination.- Specified by:
export
in interfaceExportAgent
- Specified by:
export
in classExpression
- Parameters:
out
- the expression presenter used to display the structure- Throws:
XPathException
- if the export fails, for example if an expression is found that won't work in the target environment.
-
getElaborator
public Elaborator getElaborator()
Description copied from class:Expression
Make an elaborator for this expression- Overrides:
getElaborator
in classExpression
- Returns:
- an appropriate
Elaborator
-
